Virtual reality system and method

Abstract

A novel display system for observing virtual and real images. The display system includes a light redirection surface or reflective surface (e.g, mirrored surface) to display, for example, a virtual image. The system also has a light emitting surface, or LES, which includes first and second sides directly opposite from each other. The LES emits light to form the virtual image at an apparent distance behind the reflective surface. An observing region is also included on the second side of the LES for observing the image through the LES.
